Hibiscus plant named ‘Chiffon Breeze’

ABSTRACT

A new and distinct  Hibiscus  plant named ‘Chiffon Breeze’, characterized by its compact, upright, outwardly spreading, uniform, dense and symmetrical plant habit that is appropriate for container production; glossy and dark green-colored leaves; uniform and freely flowering habit; light yellow-colored flowers with white centers; good resistance to flower bud abscission during shipping; and tolerance to pathogens common to  Hibiscus  grown under Florida production conditions.

Botanical designation: Hibiscus rosa-sinensis.

Cultivar denomination: ‘Chiffon Breeze’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the name ‘Chiffon Breeze’.

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Alva, Fla. The objective of the breeding program is to create new freely-branching Hibiscus cultivars with a dense, uniform and compact plant habit appropriate for container production, early and uniform flowering, numerous flowers per lateral branch, desirable flower color and good postproduction longevity.

The new Hibiscus originated from a cross-pollination made by the Inventor in Alva, Fla. in early 1997, of a proprietary Hibiscus rosa-sinensis selection, designated as code number YB-1388, not patented, as the female, or seed, parent with a proprietary Hibiscus rosa-sinensis selection, designated as code number YB-1470, not patented, as the male, or pollen, parent. The cultivar Chiffon Breeze was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., on Sep. 21, 1998.

Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled environment in Alva, Fla. since February, 1999, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Chiffon Breeze has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Chiffon Breeze’. These characteristics in combination distinguish ‘Chiffon Breeze’ as a new and distinct cultivar:

-   -   1. Upright, outwardly spreading, uniform, dense and symmetrical         plant habit that is appropriate for container production.     -   2. Glossy and dark green-colored leaves.     -   3. Uniform and freely flowering habit.     -   4. Light yellow-colored flowers with white centers.     -   5. Good resistance to flower bud abscission during shipping.     -   6. Tolerant to pathogens common to Hibiscus grown under Florida         production conditions.

Plants of the new Hibiscus can be compared to plants of the female parent, the proprietary Hibiscus selection code number YB-1388. Plants of the new Hibiscus differ from plants of the female parent selection primarily in flower size as plants of the new Hibiscus have larger flowers than plants of the female parent selection.

Plants of the new Hibiscus can be compared to plants of the male parent, the proprietary Hibiscus selection code number YB-1470. Plants of the new Hibiscus differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Hibiscus are not as vigorous as plants of         the male parent selection.     -   2. Plants of the new Hibiscus and the male parent selection         differ in flower color as plants of the male parent selection         have yellow-colored flowers with red centers.

Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar Cashmere Wind, disclosed in U.S. Plant Pat. No. 16,066. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of the cultivar Cashmere Wind primarily in flower color as plants of the cultivar Cashmere Wind had darker yellow-colored flowers with orange centers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hibiscus, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hibiscus.

The photograph on the first sheet comprises a side perspective view of five typical flowering plants of ‘Chiffon Breeze’ grown in a container.

The photograph on the second sheet comprises a close-up view of a typical flower of ‘Chiffon Breeze’.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Alva, Fla., with five plants per 16.5-cm container in polyethylene-covered greenhouses during the late summer under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 16 to 37° C. and night temperatures ranged from 13 to 26° C. Plants were about four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
